Command Specifications
4-20 C141-C008
If the IDD performs rounding processing ("rounding up" or "rounding down") of
parameter values specified by the INIT, in some cases a "CHECK CONDITION"
status (RECOVERED ERROR [=1] / Rounded parameter [37-00]) is reported,
and in some cases it is not reported. Whether or not a "CHECK CONDITION"
status is reported is determined by the type of "rounding up" or "rounding down"
and the conditions.
If the INIT would like to confirm that the IDD is implementing rounding
processing, it issues a MODE SENSE or MODE SENSE EXTENDED command
after issuing this command and reads the values for the "Current" parameters,
then compares them with the parameter values sent in the MODE SELECT
command.
Parameter fields which are the object of rounding processing are explained in the
descriptions of each page descriptor in this item.
Table 4.12 lists the data configuration of the parameter list transferred by the
INIT in this command. The parameter list is configured from header 4 bytes in
length followed by a block descriptor with a length of 8 bytes. This is followed
by one or more page descriptors, or, when there is no block descriptor the 4-byte
header is followed by one or more page descriptors. The INIT may transfer a
header only, or the header and block descriptor only without the page descriptor
added.
The page descriptor is processed correctly whether the supported pages are sent
individually or if all pages are sent continuously. Also, when multiple pages are
sent continuously, even if the order of each page is optional, they are executed
normally.
